Clean up lambda output from exyacc.rb
The `lambda_body` grammar rule has a `"}"`, which is throwing off the `exyacc.rb` regular expressions. This changes the regular expression to account for `"}"` as well, which makes the output of `ruby sample/exyacc.rb < parse.y` change by the following diff:
```diff
632,634d631
< ", &@3);
< $$ = $2;
< }
```
Which makes it closer to a valid EBNF.
